Teleostei (teleosts) > Tetraodontiformes (Puffers and filefishes) > Balistidae (Triggerfishes)
Etymology: Rhinecanthus: Greek, rhinos = nose + Greek, akantha = thorn (Ref. 45335).
Eponymy: Pablo Ruiz Picasso (1881–1973) was a Spanish painter and sculptor. The vivid patterns and colours of Rhinecanthus triggerfish have led to them being popularly known as picassofish. Not an eponym but reported by Forsskål as being a local Arabic name for the fish – ‘Azzazi’. (Ref. 128868), visit book page.

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.02692 (0.01290 - 0.05617), b=2.91 (2.73 - 3.09), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		4.5   ±0.13 se; based on food items.
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		Low to moderate vulnerability (31 of 100). 🛈
